3-(2,6-Dichlorophenyl)-5-methylisoxazole-4-carbonitrile CAS 21486-28-2

Description

Compared with other compounds in its class, the molecular weight of 253.08 g/mol gives 3-(2,6-Dichlorophenyl)-5-methylisoxazole-4-carbonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

3-(2,6-Dichlorophenyl)-5-methylisoxazole-4-carbonitrile (CAS 21486-28-2), molecular formula C11H6Cl2N2O and molecular weight 253.08 g/mol, is a CATO reference standard with documented purity and traceability.

3-(2,6-Dichlorophenyl)-5-methylisoxazole-4-carbonitrile (C11H6Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 3-(2,6-Dichlorophenyl)-5-methylisoxazole-4-carbonitrile under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
